Ground granulated blast-furnace slag Ground-granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.Contents.GBS cement can be added to concrete in the concrete manufacturer's batching plant, along with Portland cement, aggregates and water. The normal ratios of aggregates and water to cementitious material in the mix remain unchanged. GGBS is used as a direct replacement for Portland cement, on a one-to-one basis by weight.

- Steel Furnace Slag is produced in a (BOF) Basic Oxygen Furnace or an (EAF) Electric Arc Furnace. Hot iron (BOF) and/or scrap metal (EAF) are the primary metals to make steel in each process.Lime is injected to act as a fluxing agent. The lime combines with the silicates, aluminum oxides, magnesium oxides, manganese oxides and ferrites to form steel furnace slag, commonly called steel slag.ot iron (BOF) and/or scrap metal (EAF) are the primary metals to make steel in each process.

Utah Population 2018 By far the largest metropolitan area in the state is the Salt Lake City metropolitan area, with 1.3 million residents as of 2016. This is followed by the Odgen-Clearfield area with 597,000 residents. While Utah as a whole has a very low population density, Salt Lake city proper has a density of 1,666 people per square mile. It's worth noting that Salt Lake City, Utah, is the world headquarters of The Church of Jesus Christ of Latter-day Saints (LDS Church), and about 63% of Utahns are members of the church.

The Slag Page A blast furnace produces two products: one is the pig iron that is the marketable/usable product and the other is slag that is typically discarded at the site. It was used later for roadkill and also apparently used to make some variants of Depression Glass.last furnace slag is distinctive. It is a dense glass. The colors come both from minerals and elements within the iron ore and the fluxing agent. There is archaeo-metallurgical discussion going on as to whether the process or the ingredients or both and if so, how much of either, if any, influenced the color.

- Many of these ores also contain a large amount of silicates. When lime is mixed with the ore and the. mixture melted, these silicates combine with the lime, forming a liquid solution called slag. Slag is immiscible. with molten iron, so the silicates can be removed from the iron by draining off the slag.

What is a Granulator Richard Pyle October 5, 2010 Granulator, Plastics. It only takes a Google search on the internet to find out that the word “Granulator” is one of the most widely used terms in the size reduction industry and perhaps, one of the most misused terms.ranulators Defined. Simply put, a Granulator is a high speed, normally open rotor knife mill designed to take larger components of feed stock (such as plastics, bottles, organics, etc…) and reduce them to a particle size of approximately 40 mesh to 1/8” chip.

What are Coal Combustion By-Products (CCBs)? Bottom ash is formed in coal furnaces. It is made from agglomerated ash particles that are too large to be carried in the flue gases and fall through open grates to an ash hopper at the bottom of the furnace.

- Introduction of high quality coke to a blast furnace will result in lower coke rate, higher productivity and lower hot metal cost. The cokemaking process involves carbonization of coal to high temperatures (1100°C) in an oxygen deficient atmosphere in order to concentrate the carbon.

Slag Slag is the glass-like co-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.errous and non-ferrous smelting processes produce different slags. The smelting of copper and lead in non-ferrous smelting, for instance, is designed to remove the iron and silica that often occurs with those ores, and separates them as iron-silicate-based slags.

Iron and Steel Slag Statistics and Information In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina. From this and the added fluxing agents molten slag and iron are formed.

Does concrete melt? If concrete made with Portland cement or blast furnace slag cement is subjected to heat, a number of transformations and reactions occur, even if there is only a moderate increase in temperature.5,6 As aggregate materials normally occupy 65 to 75% of the concrete volume, the behavior of concrete at elevated temperature is strongly influenced by the aggregate type.

- excellent low density fill material, typically one-third the weight of Air cooled and expanded blast furnace slags have been used in several large volume projects. Steel slags have been used in fill applications where expansion is not an issue. Exposure to moisture may lead to chemical reactions, so care should be used when considering using steel slags under pavements or foundations where expansion may lead to poor performance.

- In the blast furnace. Blast furnace in a modern steel works. Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron oxide. The oxygen must be removed from the iron oxide to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions.

How is LD slag produced? Liquid LD slag is produced during the LD process as pig iron is processed into crude steel. Slag is not a random product, but rather a consequence of the Linz-Donawitz process, which uses steel as well as LD slag.The slag is separated from the crude steel, separately processed, and its chemical composition analyzed.D slag is a byproduct of the Linz-Donawitz process and is constantly produced as pig iron is processed into crude steel.

- Engineering properties. Some of the engineering properties of granulated blast furnace slag that are of particular interest when blast furnace slag is used as a supplementary cementitious material in Portland cement concrete include the hydraulic reactivity of the slag and its fineness.wo types of blast furnace slag such air-cooled slag and granulated slag are being generated from the steel plants. In most cases, this slag is produced in the form of granulated slag. The specific gravity of the slag is approximately 2.90 with its bulk density varying in the range of 1200 1300 kg/m3.
